Are these real credit card numbers?

No. The generated numbers pass the Luhn check used by payment forms, but they are not issued by any bank and cannot be used for real purchases.

Can I use a custom BIN prefix?

Yes. Enter the BIN (the first digits of the card) and the tool will fill in the rest and compute a valid Luhn check digit.

How does the validator work?

It strips spaces and dashes, detects the card brand from the prefix, checks the length against the brand specification, and verifies the Luhn checksum.

About this tool

This generator creates credit card numbers that satisfy the Luhn checksum and follow brand-specific prefix and length rules for Visa, MasterCard, American Express, Discover, JCB, Diners Club, and UnionPay. The numbers are useful for filling out test payment forms, exercising QA flows, and seeding sandbox payment gateways. They are not real and cannot be used for any purchase or subscription.

The validator does the reverse: strip spaces and dashes from the input, detect the brand by prefix, check that the length matches what the brand allows, and verify the Luhn checksum. Use it to sanity-check the test data your QA stack is producing.
